replace curves with ellipses

Did a trace on a JPG which converted the hundreds of circles to squares/rectangles/random curves. I cannot find anything that allows me to replace the white curves with pink circles/ellipses. There are too many to do it manually with copy-paste & align. Sample area, shown.

Thank you. That's better but still not ellipses/circles. I used the same settings except had Detail to 100%. Hate to say it but I found an easy fix using Illustrator 2020. I selected the white areas, went to "Objects" "Convert to Shape" "Ellipse" and it was done. If there is a comparable feature in CorelDraw 2019, I couldn't find it. Really prefer to use Corel but in this case AI was the winner.
